BB450 is a moisture vapor barrier film developed by the engineers at Bennett & Bennett.

Cleaned inside cleanrooms, these bags can be shipped clean to Level 100.

Why choose BB450 versus other films? BB450’s proprietary dual layer polyethylene-nylon lamination is transparent, does not stretch, and is capable of maintaining a high moisture and gas barrier over the duration of an international shipment. With over 25 years experience in building cleanrooms, manufacturing the film, and cleaning it at our facilities why trust your finished product to people who aren’t cleanroom experts?
